not happy with magnaflow

it sounds like ass, its not loud enough and raspy...

stock manifolds, no cat...

im about to buy the borla, but is there a huge difference in sound? im prolly gunna run open plates ;)

sell me your magnaflow...

The Borla will sound nice and quality is top notch.The rasp that is occuring is probably due to the fact that you're not running a cat.
Regards,Mark.

You could always install a cat to remove the rasp and you could fit an electric cut-out to up the volume when you the mood takes you.
My exhaust is loud even with a cat installed :).
Is the Magnaflow brand new ?

magnaflow been on for 6 months, never seen rain, and polished once a month lol. yes it looks brand new.

do you mean it's not loud and it's raspy? or it's not loud... and it's not raspy?

Umm yea my magnaflow sounded awsome on stock mani w/ no cats...and even better on LT's....I dont know what the big deal is w/ rasp. Its a damn v8, if you were running straight pipes you'd probably say that it sounded raspy. Dont change the muffler if you cant deal w/ rasp. Anything will sound raspy at 5k...come on..think about.

get a small bullet muffler in place of the cat if you dont want the rasp. It will help out lots, or you could run a cat again, your choice.

What are you really looking for out of your exhaust? Borla is very expensive and there are many other options out there.

i'll so take your magnaflow off your hands

borla is going to be even more rapsy. your first post is a little confusing. your problem is the stock manifolds and no cat. its going to sound terrible no matter which muffler you go with.

i have a similar setup...stock manifolds, Stainless works o/r y-pipe,,,dynomax bullet res. instead of cat,, and a magnaflow muffler , with the 2otl outlet and single inlet,,,,,

just throw a bullet and it will sound fine,,,alot less popping and cracking with the bullet

you think your magnaflow is too raspy so you want a borla instead? LMFAO.

that's like saying your stock exhaust is too loud so your gonna run straight headers instead.

get some LTs it will solve your issues!

i think im putting a cat on because it really sounds like ****.

are you sure you don't have an exhaust leak? why go backwards get some LTs! I had Magnaflow on my factory cat forward car and it sounded fine...

post a sound file

Borla sounds like arse with the open plate. It's not going to solve your problem.

so what exactly would it sound like without the bullet,,,so i would run just the offroad y-pipe and the magnaflow muffler

im tempted to take the bullet off

I have stock mani's, a gutted cat and a magnaflow and it sounds ok. It is a bit raspy on hard accel but I think it sounds cool. Still I think I am gunna put a flowmaster 40 on there, and some long tubes.

i had a flowmaster 40 on mine previous to the magnaflow ,,the mag sounds alot better than the flow

I did this and the bullet muffler failed in 6 months from the extreme heat just post manifolds, or in my case headers. The insides started deforming, then it fell apart.

Running no cats makes some rasp. Its not the magnaflow. Even my Borla had some without cats.

I destroyed my cats running a D1 on 383ci LT1. Removed them and ran 2 1/2 straight thru pipe. Lots of bad resonance @ 2k to 2.5k rpm on a Spintech 3 1/2 muffler. Could not live with it. I did a 3 1/2" cc 3-disc insert in the pipe before the axle. No more resonance and did lower the noise. I still open 3 1/2" qtp when I need to for max flow.

I have LT's, Off road Y-pipe and a Magnaflow cat back and I like the sound of it but it is just not as loud as I expected it to be. Maybe I am just used to hanging around to many Mustangs.

i took off my bullet resonator thursday ,,it sounds about the same as before just alot louder

Definatly dont go Borla if you dont want rasp. I just did LT's, no cats, on Borla and it is LOUD and raspy at 2000-2500 rpm range. Im looking to add a bullit muffler of just change to something else.

this thread keeps getting resurrected from the dead over and over and over and over.....

If you're complaining about raasp w/ no cats on a Magnaflow, you'll hate the Borla.. I had one for years.. LT's ORY w/ no plate and it was all rasp..

People who complain about rasp on a free flowing exhaust are just dumb..its the nature of the engine. Go throw some parts on to help restrict power if you dont like rasp.

my kooks/gmmg doesn't have much rasp... I don't think it's restrictive?

Just add some LTs to the mix, then you'll have no rasp.:D

^ LT's and magnaflow sounds awsome

^ LT's and magnaflow+cutout sounds awsome:devil:

I added a 12" 4"round dynomax bullet to mine today and it took all the rasp out. My car sounds great now.

Still a little rasp, not near as loud at idle and cruising(nicely) thru town but still sounds like holy hell when you get on it. I was forced to use these because of a police officer who just loved me....Not a complaint and I have had no adverse effects using them.
Here is a link for a vid of my car minutes before I started my next build.

a dynomax bullet is alot cheaper, $40 something at summit and NO rasp.
